The discovery of a body raises questions: The man, missing for two years, was buried two meters deep in the earth in the floodplain near Nuremberg. Andreas Schönfeld, a 37-year-old bicycle dealer at the time of his death, was considered friendly and popular with his neighbors, yet Franconian investigators discover that he had no close friends. Chief Inspector Felix Voss - in his first case without his long-time partner Paula Ringelhahn, but strongly supported by Wanda Goldwasser and his current driver Fred - wonders: What connections led to the bicycle dealer's gruesome death? A visit to the victim's mother, Erika Schönfeld, reveals a loving mother-son relationship, and the pain is immense. In their further attempt to reconstruct Schönfeld's life, Felix and Wanda encounter the blind Lisa Blum.
